Across the river bank, cars of all sizes are driving on the bridge one after another. We can easily cross the bridge to the other side. With such a long bridge and so many cars, the bridge is still empty. Why can the bridges on both sides bear so much weight like wooden boards and not collapse? I wonder: Why won't the bridge collapse? I don't understand, so I asked my mother. My mother is also speechless and can't answer. She asked me to find the answer myself and suggested that I could consult the teacher. I thought a lot and decided to find the answer from mathematics. I turned my attention to math class.
After listening to the teacher's triangle in the class of "Understanding Graphics", I suddenly realized. It turns out that most of the chains on the bridge are drawn as triangles, which are stable. No wonder the chain on the bridge is triangular, so the bridge won't fall down.
There is mathematics everywhere in life. If you watch carefully, you will find the mystery of mathematics in life. It's good to learn math! I must study math!
